I've been having a few issues in the last couple of days. I usually get a headache at night time, usually from around 10pm. Also, when I turn my head, there's a strange time aspect and feeling to it, where I feel its turning but time also slows down. Anyone experienced anything similar or have any idea why this is happening?

It could be the painkillers causing that odd time-delay feeling. I was on painkillers for my wisdom teeth for a while and I found anything with codeine in it tended to make me feel light-headed and a bit off-kilter.

I've heard that taking painkillers can actually make the headaches worse, as you get "rebound headaches". I guess as the painkiller wears off, the headache comes back, so you need to take more, etc etc. I know, I got stuck in that cycle, I just lived on panadols, took them like lollies, but after a while they just stopped working! But I was having headaches every day for over 6 months....

Maybe try to stop taking the painkillers and see if you can discover the real cause of the pain. The drugs are just a bandaid unfortunately

I had been getting headaches everyday for weeks & wasn't taking any pain killers as they just didn't work. They were getting worse at night times & the light was affecting me. I went to the doctor & he asked me when the last time I had my eyes checked which was over 2 years ago. Found out all it was I needed much stronger glasses so had bad eye strain daily.So it could be as simple as needing glasses or it could be serious, either way get it checked out by a doctor.
